Jeb Bush explains staff shake-up ahead of White House bid launch

By Michelle Martin BERLIN (Reuters) – Former Florida Governor Jeb Bush on Wednesday explained a shake-up of his political team, saying he was trying to ensure that his staff all had roles suited to their skills as he prepares to launch his presidential bid. Earlier this week, Bush picked Danny Diaz, a veteran of Republican politics, as his campaign manager in what was seen as a surprise move. David Kochel, another experienced political strategist, was believed to have been penciled in for the role when he was hired this year.
